Rohan has a feeling that Josuke is cheating at cee-lo, and cuts off his own pinky. If he is unable to figure out Josuke's trick in the next round, he says he will pay him 2 million yen to have him use Shining Diamond to fix his finger. But if Rohan does figure it out, he says he'll take Josuke's pinky instead. He even calls Tamami to act as a mediator, having him use his Stand ability so Josuke can't play fairly the next round, either.
Up until now, I've held back 
my anger toward you
حتّى اللّحظة، كنتُ أكبح جماح غضبي تجاهك
Bis jetzt habe ich Herrn Joestar und Kōichi zuliebe
 meinen Zorn gegen dich in Zaum gehalten,
He contenido mi antipatía hacia ti
por respeto a Koichi y al señor Joestar,
He contenido mi antipatía hacia ti
por respeto a Koichi y al señor Joestar,
Jusque-là, je me suis retenu
par respect pour M. Joestar et Koichi,
È solo per il bene del signor Joestar e di Koichi
che finora mi ero sforzato di sopportarti,
Até então, eu segurei a fúria
que sinto por você
